Questions

Frequently asked questions

Is Summerville tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Summerville, PFOS 8.1 ng/L and PFOA 6.2 ng/L were measured above the 4 ng/L federal limit in EPA's 2024 testing; the lead 90th-percentile result was 0.3 µg/L against the 15 µg/L action level. SUMMERVILLE CPW (SC1810003) (PWSID SC1810003) has a Purity Score of 57/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.

Who provides tap water in Summerville?

SUMMERVILLE CPW (SC1810003) (PWS ID SC1810003) is the public water system on record for Summerville, South Carolina, serving about 81,750 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Summerville get its drinking water?

Surface water (primary source of record in EPA SDWIS).

Are PFAS "forever chemicals" in Summerville's water?

Yes. In EPA's UCMR 5 testing (2024-09-17 to 2025-06-17), PFOS was measured at 8.1 ng/L against a 4 ng/L federal limit and PFOA was measured at 6.2 ng/L against a 4 ng/L federal limit. PFBS (4.4 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxA (5.9 ng/L, below the 400,000 ng/L state limit) were also detected. PFBA (5.1 ng/L) and PFPeA (6.6 ng/L) were also detected; they have no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.

Is there lead in Summerville's tap water?

SUMMERVILLE CPW (SC1810003)'s most recent lead 90th-percentile result (2024–2026) was 0.3 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.

What does the latest Summerville water report show?

PurityMap's current record for Summerville holds 31 findings: 2 above a reference, 3 detected within the reference, 2 detected with no limit and 24 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
